Arvika Westlanda airport does not have a METAR station. This page uses the weather data provided by the SMHI station next to the field. The station updates once per hour and there are no guarantees about the accuracy. The same applies to Sunne / ESKU and Arjang/Blomskog (not an airfield). This page only presents the data in a format pilots are comfortable with. Source for nearby METARS: AROWeb.
Please use this resource to determine whether it's worth going out to the airport and checking for yourself but never rely on the accuracy of this data for flight planning and decisions.
